Why is Nvidia so important?published at 00:41 GMT
US tech giant Nvidia is the world's most valuable publicly-traded company - worth some $4.5tn (£3.4tn) - and a leading provider of advanced computer chips.
These computer chips are critical for all kinds of technology - from video games and autonomous vehicles to massive data centres and cloud servers.
But most importantly for the AI arms race, these chips are used to power artificial intelligence, including large language models and generative AI systems.
The US's biggest competitor in the race to build the most powerful AI systems is China, and Washington has restricted exports of the most advanced Nvidia chips to Beijing since 2022.
The US has justified export restrictions on national security grounds, arguing that such exports could enhance China's military capabilities, although some restrictions have been eased under President Trump.
